This 2001 Ford ExST, like most 1997+Later Autos, has an OnBoardDiagnosis2 ComsPort under the left Dash.
After keeping a basic OBD2 Scanner in the GloveBox for several years that reads & resets only StandardSAE
TroubleCodes, I now also use these items that allow for complete access to all Codes, Signals & Configurations:

OBDLink#MXP OBD2~WirelessBT ComsModule & OBDLink+Torque+Carista Apps & AndroidPhon
* Reads+Resets+Graphs both StandardSAE & ProprietaryAutoMaker Codes.
* DashBoardMode for viewing Temps & Signals while driving.
* Used for Routine Maintenance & DailyMonitoring.

OBDLink#EX OBD2~CabledUSB ComsModule & OBDLink+ForScan Apps & WindowsPC
* Reads+Resets+Graphs+Configures both StandardSAE & ProprietaryAutoMaker Codes.
* Faster & easier than ToggleSwitch ELM327 ComsModules.
* Used for InDepth Maintenance & Configurations.
